If you'll recall, Season 2 ended with our favorite red-headed athlete-turned-musician being framed for murder by Hiram Lodge. Aguirre-Sacasa told Entertainment Weekly that the third season opens with Archie’s murder trial coming to a close (we got some preview pics of the trial yesterday).

“It’s Labor Day weekend and it’s closing arguments for Archie’s trial,” Aguirre-Sacasa told the publication, adding that “in the premiere episode, the outcome of the trial will be revealed.”

If you think that’s abrupt, remember that the show still has a slew of other dangling plot threads it must address — including a new mystery — so it doesn’t have time to spend all season in a courtroom doing its best Law & Order impression. This is Riverdale, after all. These new crime sprees aren’t going to solve themselves, you know.

And as for that flashback episode that Aguirre-Sacasa announced at Comic-Con, where we’ll see the parents of Riverdale as high schoolers — played, of course, by the actors who play their children? Well, the Riverdale executive producer said the kids discover that history may be repeating itself in more ways than one. You see, not only was a similar murder committed in the past to one in the present day, but it also appears that the previous generation also had an affinity for an off-brand Dungeons & Dragons role-playing game.

“The murder victims in the present were playing a game called Griffins & Gargoyles, which is, of course, the Riverdale version of Dungeons & Dragons,” said Aguirre-Sacasa. “Our kids discover that when their parents were in high school they also were playing this game, and there was a similar murder that happened in the past.”

Actress Lili Reinhart, who plays Betty and the teenage version of her mother, Alice Cooper (played as an adult by Mädchen Amick) told EW that she won’t just be doing an impersonation of Amick’s portrayal of the character, because Alice as a teen was “so different from the Alice that you see today.”

“She’s not just this uptight, precocious, looks-down-upon-everyone teen,” Reinhart added. “She was a Serpent.”

All this teasing was just about two episodes in the third season. If the second season is anything to go by, there’s much, much more to look forward to.

Riverdale returns to The CW for its third season, with all its insane plotlines and mysteries, beginning Oct. 10, with the flashback episode airing Nov. 7.
